Class B Data Communication Network Messages - Part 2: Data Parameter Definitions

Vehicle Architecture For Data Communications Standards

The ever-increasing consumer expectations of vehicle internal functions and connectivity to the environment are outstripping the capability of current data communication architecture design. To address this vulnerability, this committee will investigate and endorse new vehicle architectures that meet system requirements such as: Reliability, System design metrics, Data security, Fault Tolerance, Built in testability, Validation/Verification , Compatibility, and Redundancy. This committee's mission is the investigation and development of vehicle architecture and data communication protocols and methods required to achieve the growth expected in the area of vehicle electronics. The committee shall continue to contribute to the understanding and use of semiconductor devices such as microprocessors, power devices, and other integrated circuits and the data transmission media used in these systems. Thus, all vehicle architectures (excluding aircraft) and devices used in these systems shall be included. Specific objectives shall include: Address the effect of electrical power environments (e.g., 42V, ground offsets) , Sponsor forums to evaluate new technologies (e.g., MOST, Bluetooth, Firewire), Publish technical reports on vehicle architecture and system partitioning, interfacing, modes of operation, protocol standards, recommended conformance test methods, and evaluation methods of those standards , Maintain the existing documents relevant to this committee (e.g., glossary of automotive electronics terms, SAE J1213/1), Encourage the applicable industries, government and educational institutions to support the efforts of this committee.
